Token Wrapper Features
Most DeFi contracts cannot handle a native coin directly — they expect a token that follows the standard, with a balance and an allowance. Wrapping deposits your native coin into that contract and gives you the wrapped version one-to-one; unwrapping reverses it. Smithii does both on nine networks from one form, and the rate is always exactly one to one.
Always one to one
Wrapping is a deposit, not a swap: no slippage, no price, no route. One native coin in, one wrapped out, and back again whenever you want.
Nine networks, one form
Solana and eight EVM chains. The selector picks the network and the wrapped token for it — wSOL, WETH, WBNB, WPOL, WAVAX.
Straight to the canonical contract
Each network has one wrapped contract that every DEX and protocol recognises. The tool uses that one, so the balance is usable everywhere.
Why use Token Wrapper?
One to one, always — wrapping is a deposit, not a trade.
Nine networks from the same form.
Uses each network canonical wrapped contract, the one protocols expect.
Unwrap back to native whenever you want, same rate.
Non-custodial: the wrapped balance is in your own wallet.
No approval dance — wrapping needs no allowance because it is a deposit.

Depositing a native coin into a contract that gives you a standard token backed one to one by it. The wrapped version works in contracts that cannot handle native coin directly.
Yes. Wrapping is a deposit, not a trade — there is no price, no slippage and no route. Unwrapping returns the same amount.
Network gas, plus the Smithii fee where one applies — see the comparison table above. There is no spread, because nothing is being traded.
| Network | Fee | Native → wrapped | Explorer |
|---|---|---|---|
| Solana | 0.001 SOL | SOL → wSOL | Solscan |
| Ethereum | 0.00012 ETH | ETH → WETH | Etherscan |
| Base | 0.00012 ETH | ETH → WETH | BaseScan |
| BNB Chain | 0.0004 BNB | BNB → WBNB | BscScan |
| Polygon | 2.7 POL | POL → WPOL | PolygonScan |
| Arbitrum | 0.00012 ETH | ETH → WETH | Arbiscan |
| Avalanche | 0.035 AVAX | AVAX → WAVAX | Snowtrace |
| Blast | 0.00012 ETH | ETH → WETH | BlastScan |
| Robinhood | 0.00012 ETH | ETH → WETH | Blockscout |
Yes, at any time and at the same one-to-one rate, from the same form.
No. Wrapped ETH is ETH deposited in a contract on the same network, redeemable one to one. Bridged ETH is a claim on another network backed by a bridge, and carries that bridge as risk.
Solana and eight EVM chains. The wrapped token for each is listed in the comparison table above. Sui is not supported.
Not to wrap — a deposit needs no allowance. Spending the wrapped token in another protocol may need an approval, as any token would.
Why wrapping exists at all
A native coin — SOL, ETH, BNB — is not a token. It has no contract, no balance function and no allowance, because it is the network money itself. Token standards came later, and almost every DeFi contract is written against them.
Wrapping bridges that gap by depositing native coin into a contract that mints a standard token against it. That token behaves like every other token, which is the entire point: pools, lending markets and routers can handle it without special cases.
When you actually need to wrap
Adding liquidity to a pair that quotes in the wrapped version, supplying to a lending market, or interacting with a contract that only accepts tokens. Most DEX interfaces wrap silently in the background, which is why many people never wrap by hand.
You need to do it explicitly when you are dealing with a contract directly, when a tool asks for the wrapped token, or when you are left holding a wrapped balance you want back as native.
Wrapped is not bridged
Wrapped ETH on Ethereum is ETH deposited in a contract on Ethereum, redeemable one to one at any time. Bridged ETH on another network is a claim backed by a bridge, and its risk is the bridge.
The names look alike and the risk does not. Wrapping carries the risk of one well-known contract per network; bridging carries the risk of whoever runs the bridge.
